Woźniki Wastewater Treatment Plant | Woźniki, Silesian Voivodeship, Poland

The Woźniki wastewater treatment plant is located in the town of Woźniki, in the Silesian Voivodeship of southern Poland. It serves a population of 660 and operates with secondary treatment, which is the standard biological treatment for small agglomerations under Polish and EU regulations. With a designed capacity of 1305 cubic meters per day and an average daily discharge of 94.11 cubic meters, the plant operates well below its capacity. As a small facility in Poland, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent above 2000. For smaller plants like Woźniki, secondary treatment is still recommended to protect local water quality. The plant's treated effluent is discharged into local waterways that eventually drain into the Baltic Sea via the Vistula River basin. The surrounding region is characterized by mixed agricultural and forested landscapes, and the plant plays a key role in preventing nutrient pollution in the local watershed.

The Woźniki plant discharges into small streams that flow into the Liswarta River, a tributary of the Warta River, which ultimately drains into the Oder River and then the Baltic Sea. The local watershed supports diverse aquatic life and is part of a region with sensitive ecosystems, including areas important for migratory birds. Proper treatment helps reduce nutrient loading and protects downstream water quality.
